Answer:
y = -2x -9
Step-by-step explanation:
<h2><u>in order to solve this question you have to do the following : </u></h2>
1. find the midpoint of the coordinates given
2. find the gradient of the line
3. make the equation
<h3><em><u>STEP : The midpoint </u></em></h3>
formula of the midpoint is
now place the values in the equation :
midpoint = ( -3 , -3)
<h3><em><u>STEP 2 : The gradient </u></em></h3>
formula of finding the gradient
insert the values in the equation:
=
gradient = -2
<h3><em><u>STEP 3: Form the equation </u></em></h3>
use the formula of the equation :
now make use of the gradient(m) and the midpoints and insert into the equation
(y-(-3)) = -2(x -(-3))
hence
y+3 = -2 (x +3)
y= -2x -6 -3
<h3><u /></h3><h3><u>y = -2x -9 </u></h3>
